What happens
Laertes prepares to leave for France and warns his sister Ophelia against Hamlet's advances, claiming his affection is merely a passing fancy that will fade. Polonius enters and blesses Laertes, delivering a lengthy speech of practical advice about conduct abroad. After Laertes departs, Polonius interrogates Ophelia about Hamlet, dismisses the prince's intentions as insincere, and forbids her from seeing him, commanding her to value herself more highly and reject his overtures.
Why it matters
This scene establishes the machinery of surveillance and control that will drive much of the play's tragedy. Laertes and Polonius frame Hamlet's love as predatory and false, a young man's thoughtless seduction of a girl beneath his station. Their warnings are not entirely wrong—Hamlet is unstable—but they reduce Ophelia to a pawn, treating her agency as something to be managed rather than respected. Polonius's famous speech on how to conduct oneself in France, while seemingly fatherly advice, reveals his obsession with appearance and reputation over genuine feeling. His instruction to spy on Laertes ('By indirections find directions out') shows his method: he gathers intelligence through deception, a habit that will later position him fatally behind the arras in Gertrude's chamber.
Ophelia's compliance in this scene is her undoing. She accepts her father's and brother's judgment without protest, surrendering her own judgment to their authority. When she promises to obey Polonius's command to reject Hamlet, she seals her fate—caught between the two men who claim to protect her. The scene's power lies in its quiet tragedy: Ophelia is intelligent enough to recognize the contradiction in Laertes's own hypocrisy (he warns her against lust while heading to France himself), yet she has no power to resist. By the play's end, robbed of agency and crushed by the men around her, she will drown in the very passivity this scene demands of her.
